- (Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:(General math) a. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The subroutine should determine and return the hypotenuse, c, of the triangle. (Hint:UsePythagorastheorem,c2=a2+b2.) b. Include the function written for Exercise 4a in a working program. The main() function should call rightTriangle() correctly and display the value the function returns.4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }
- In C/C++, True or False: A function that changes the value of a variable passed by reference also changes the value of the original variable. A variable's type helps define the amount of memory it takes to hold a value of that type.Computer Science R programming Adjust your functions to take into account upper and lower case letters, as well as spaces. Bonus: can your functions also deal with special characters. Apply your first function to the variable x1 and then the second function to your output, so you can convert it back. x1 <- "Hello My Friend" x2 <- "This: Is, Comma: Horror!"Plants Growth Cycle Learning Objectives In this lab, you will practice: Defining a function to match the given specifications Calling the function in your program Using if statements (can combine them with dictionaries) Instructions For every plant, there is a growth cycle. The number of days that it takes starting from being a seed and ending in being a fruit is what is called the growth cycle. Write a function that takes a plant's name as an argument and returns its growth cycle (in days). In your program: Input from the user the name of a plant Check if the input is either "strawberry", "cucumber" or "potato", if Yes: 2.1 Call calculate_growth_cycle 2.2. In function calculate_growth_cycle, check over the plant's name: 2.2.1 If strawberry, print "### The life cycle of a strawberry ###" and return 110 2.2.2 If cucumber, print "### The life cycle of a cucumber ###" and return 76 2.2.3 If potato, print "### The life cycle a potato ###" and return 120 2.3 With the growth cycle…
- Future Investment Value = investment amount * (1 + monthly interest)^(number of years * 12) Using this formula, write a function in Python called futureValue that prompts the user to enter an investment amount, an annual percentage interest rate, and the amount of years. The function should accept the input as arguments. The interest rate should have a default value of 7%. You can add default values of your choice for the amount of years. This function should print out a table that displays the future values. Demonstrate this function in another function called main. Format your output by two decimal places. Output Example: Enter the amount you want to invest: 1000 [Enter] Enter the interest rate for your investment: [Enter] Enter the number of years you want to invest this money: 30 [Enter] Years Future Value 1 1093.81 2 1196.41 ........ 30 14730.58slope(x1, y1, x2, y2) that calculates the slope of the line that connects the two points. The function returns the slope to the main program. If the slope is undefined, your function should return the word “undefined”. Test the function in the main part of the program with the following values and print the results:C++ Exercise 1 (function overload):Write a program that allows you to enter three variables X, Y and Z with:• X and Y are two integers and Z is a real.• Input will be done using three different functions that have the samename Enter.• X must be positive, Y and Z must be between two passed valuesin parameters.
- Passwords, again Learning objectives In this lab, you will practice: writing a function to match the specifications using string concatenation to generate a new return value writing your code a module Instructions Write a function create_password(pet_name, fav_number) that will return a password with the following pattern: : fav_number followed by the pet_name followed by the underscore and fav_number (see example below). Create a program that reads pet name and favorite number from the user, uses the function above, and uses the return value to output: Your new password is "3Angel_3". Example Input: Angel 3 Output: Your new password is "3Angel_3". Note: Your program must define and call the following function: def create_password(pet_name, fav_number) # Define your function here. if __name__ == '__main__': # Type your code here.Passwords, again Learning objectives In this lab, you will practice: writing a function to match the specifications using string concatenation to generate a new return value writing your code a module Instructions Write a function create_password(pet_name, fav_number) that will return a password with the following pattern: : fav_number followed by the pet_name followed by the underscore and fav_number (see example below).
